We were interested in looking into the different materials that could be used to make the dome section of the mid-high range driver in our large speaker system – the Sirius. Diamond and ceramics had to be ruled out, as these are neither available in the necessary size nor as compression drivers. The high level of efficiency of a compression driver is essential for our omnidirectional horn loudspeakers, as we would only achieve an abysmal acoustic result with a conventional driver.
The most dimensionally stable and at the same time lightest metal which can be used for speaker membranes of this size is beryllium. Needless to say, beryllium is a welcome upgrade for any loudspeaker.
A new process makes it possible to roll beryllium into a wafer-thin film (truextend material). By applying extreme heat and high pressure, the metal atoms are forced into a highly uniform grain structure. Due to the tensile strength and service life of a dome produced in this way, installation in a pressure chamber driver is not only finally possible but also extremely useful for minimizing various partial vibrations, among other things.
Our latest project, the Sirius BE, combines the advantages of a beryllium mid-high compression driver with the acoustically and visually exceptional acrylic horns. These are milled from a solid piece, polished to a high gloss in elaborate manual work and impress with their immense weight alone. Acrylic is twice as dense as wood, for example, and therefore has a rigidity and inertia that does not allow any natural vibrations (opposite -> bell/sound shell). The high internal damping guarantees that the sound of the music reaches the ear as optimally and unaltered as possible.
We apply a great deal of care, meticulousness and even more listening hours in the form of a series crossover that has been sophisticated for decades, the tuning to the bass driver and the optimum housing.
Let the playful ease and attention to detail of the uncompromising sound of a Sirius BE take you on a journey through music.

Feedback:
Not just that Markus said it would be again another world of engaging deplacement drivers in a complex Horn/Omnidirectional Stero loudspeaker (which I would call only and simply the definite way of how to express natural sound), but also do these monsters handle with a (From Markus, never say anything they cannot do, Duevel). Power one can be afraid of!!!
I hooked up the new T+A PA 3100 HV Plus it’s extra power sysnchron Booster T+A PS 3000 HV (HV=high voltage J-Fets) to have a true 1000 Watts per channel in real-time.
Guess what happened?
The Duevel Sirius BE (Berillium) overexaturated whatever had been said before! At an even of roughly constant 975 Watts per channel the Berillum high/middrivers started performing at their best:
Christal clear, begging for more!!!
And after a few minutes even the huge lower frequency driver „got warm“.
The result even with more thanDas double of what Markus said his speakers can handle, they did the absolute best performance.
Presenting the statement: Show me an Amplifier that can handle me!
Well, The T+A system shut down because of overheating!
I am sure that 400 Watts RMS is just not the right technicall information. It should read: greater than 1000 Watts RMS is just suitable to get them speakers going. You might wanna cover your ears before exceeding that number.
A Fan.
Es fällt sehr schwer den Klang der Sirius adäquat mit Worten zu beschreiben, mir fällt eigentlich nur das Attribut NATÜRLICH ein. Exemplarisch fällt dies bei dem natürlichsten Instrument das wir kennen auf: Der menschlichen Stimme. Ich habe diese Natürlichkeit so noch nie über einen Lautsprecher vernommen, ich bin restlos begeistert (Beryllium sie Dank ?). Und dann die Raumabbildung, sie fühlt, sie hört sich so echt an – einfach perfekt, wer mehr möchte muss in einen Konzertsaal gehen. Wobei ich mir nicht sicher bin was Besser ist (da ein Huster, dort ein raschelndes Bonbonpapier etc.). Wer braucht da Mehrkanal (für Musik) oder soll ich mir jetzt vorstellen was vier, respektive fünf Sirius zaubern?
Sie haben einen begeisterten Kunden gewonnen, der sich sehr herzlich bei Ihnen für Ihre grandiose Schöpfung und Ihren Service bedankt und Ihnen alles Gute wünscht.
